IMPROVEMENT IN MlDDLlNGS-SEPARATORS.

Specification forming part of Letters Patent No. 127,727, dated June 11, 1872.

Specification describing certain Improvements in Machines for Separating and Purifying Middlings, invented by EDWARD YEAG- LY, of West Earl, in the county of Lancaster and State of Pennsylvania.

The nature of my invention consists in subjecting the ground material as it comes from the stones to the direct blast of a fan, so arranged as to drive a current of air of any desired degree of force horizontally over the top of a series of hopper-like chambers, into which the ground material drops, governed by its specificgravity, assorted in quality, and finds its way to the conveyers side by side, which are provided with tipping-valves to each section, and the several spouts and elevators for drawing off the feed returning to the head of the machine or other desirable joint, as the nature of the case may dictate, all combined forming a simple, cheap, and superior middlings-separator.

In the accompanying drawing, Figure 1 is a side elevation of a machine embodying my invention; Fig. 2, the front end or plan view; Fig. 3, top view of .the hopper-like chambers; Fig. 4, a longitudinal section; Fig. 5, rear or end view of the same.

Figure 1 shows the external divisions A, the fan-chamber F, and series of hoppers in the upper portion, with a lid, a; 0, an intermediate spout and valve connection with the hoppers, directly over the conveyer-chambers B. The strap-pulley D, which drives the fan-pulley E, the adjusting-slide P, spouts O and N, elevator G, and hopper H, are shown.

The hopper-like chambers 1, 2-, 3, 4, 5, and 6- are in close contact at their upper edge on a level with the fan-shaft or slightly above it, so as to afiord a clear space above said chambers within the external case A. These chambers incline toward the center, and open to the lower chambers U, which are provided with tipping-valves V, so as to turn the contents of each respective hopper into the right-hand or left-hand department of the conveyers T, and

' the said contents are carried off by the convoyers through the rear-end spouts N as feed or other quality of flour; as also from either side, the contents pass into the elevators Gby spouts O O, and return to the head of the machine throughi and into the hopper H. The bevelgearsL are arranged on the shafts lof the ordinary conveyers T, each in its respective chamber, which are provided with the ordinary slide-valves, and the tilting or tipping valves V. The bevel-pinions M on the driving-shaft, with its belt-pulleys D and K, give motion to the conveyers T in the ordinary manner. The pulley D drives the pulley E on the fanshaft to produce the blast. The outer pulley K connects by a strap with pulleyW to drive the elevators in the box G. In Fig. 5 I show a sliding gate, R, to open or close more or less the space above the hopper-chambers in the case; I l, the shafts of the conveyers; N, the spout to each, with its valvegate.

The machine is simple in its arrangement, and differs substantially from other machines for separating middlings in the application of a direct blast horizontally over all the chambers made in a direct line, instead of performing its function by suction, and which greatly complicates the machinery without adequate advantage. By this arrangement much expense is saved in the construction, and the machine is verily believed to be more efficient and more easily managed, and hence as a whole an improvement.

What I consider new in middlings-separators, and wish to secure by Letters Patent,

The series of hopper-shaped chambers 1, 2, 3, &c., provided with tipping-rvalves V, the fan F, wind-trunk X, conveyers T, spouts N O O, elevator G, and hopper H, all combined and arranged to operate substantially in the manner and for the purpose set forth.
